Executive SummaryUpdated on Dec 17, 2024

A10 Networks Thunder ADC and HAProxy compete in the load balancing and traffic management category. A10 Networks holds the upper hand due to its robust security features and integrated licensing compared to HAProxy's open-source and customizable approach lacking inbuilt security.

Features: A10 Networks Thunder ADC offers an all-inclusive licensing model, advanced traffic management, and optional security features through third-party firewalls. It provides DDoS protection and IPv6 support. HAProxy provides efficient load balancing, protocol-level traffic handling, and advanced LB algorithms, focusing on customization through scripting.

Room for Improvement: A10 Networks faces challenges with limited third-party integrations and potential support delays due to overseas centers. HAProxy needs improved logging, user-friendly documentation, and robust security features, with a more modular design and native cluster support.

Ease of Deployment and Customer Service: A10 Networks boasts strong support, although some users note response delays. On-premises deployment is common and support services receive positive ratings. HAProxy enables flexible deployment across environments but relies heavily on community support, with paid support available for critical needs.

Pricing and ROI: A10 Networks is cost-effective compared to F5, offering an ROI through simplified configuration and reduced operational costs. HAProxy's open-source nature results in affordability, with expenses focused on optional paid support or advanced features, providing a cost-effective solution for performant load balancing.

Known for its load balancing capabilities, the WAF features need to be improved

The solution's initial setup process was easy. For the installation, it takes around five minutes. One person can do the maintenance since it is not required much. So, it's a one-time solution, and its maintenance is fine. The number of people required for maintenance depends on the clients as well. One or two engineers are fine to serve around a hundred clients. If you have a number of devices, more people are needed for their maintenance because of the patching it requires during regular operations. Only for the maintenance, one engineer's fine. However, for regular operations, we need multiple people.

Useful for for small and quick load-balancing tasks

What I like best about the product is its simplicity and speed. When you need to set up a load balancer quickly, HAProxy offers options like sticky sessions and round-robin. It's also fast to configure, including adding SSL for security. While it may have fewer options than other solutions like F5, HAProxy gets the job done for basic load-balancing tasks. The reliability features of HAProxy were particularly useful in a scenario where I needed to test load balancing between two Tomcats. Since these domains were inaccessible, I set up a third Docker with HAProxy, which had access to the Tomcat domains. I then configured HAProxy to handle the load balancing. This setup allowed the client to interact with HAProxy. The solution's integration with other elements is easy.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The solution is flexible."

"The most valuable features in A10 Networks Thunder ADC are the ease of configuration, user-friendliness, and simplicity to sell to customers."

"It's a very friendly solution, easy to configure and it's very flexible."

"The ease of use is very good. It's very robust. It just sits and works."

"It is very useful to have a simple dashboard where you can login and look into what your traffic patterns are, then look and see what times of day you're experiencing the heaviest traffic. You can quickly identify if you are possibly having a security issue or security breach. It makes it very easy to use the box."

"Compared to F5, which I used about six years ago, the A10 is much easier when routing. You don't have to use the wildcard bits to route it between the different segments. It's much less troublesome to configure."

"The Deterministic CGNAT feature is valuable for us."

"The solution is user-friendly and the CLA troubleshooting is easier compared to other solutions."

More A10 Networks Thunder ADC pros

"The technical support has been, in one word, perfect. Every time I call, I’m on the phone with a representative within five minutes who is highly skilled and willing to help, whether in the case of critical issues or simple advice."

"The ability to handle a sequence of front- and back-ends gives the user the opportunity to send traffic through different services."

"Advanced traffic rules, including stick tables and ACLs, which allow me to shape traffic while it's load balanced."

"Tech support is super-quick to respond, and always on target with answers specific to the current issue."

"I estimate that this product has saved our company hundreds, if not thousands, of dollars in possible downtime from previous load balancers. We make a lot of our money from online sales, so it is critical to have 99.9% uptime."

"The most important features would be the load-balancing of HTTP and TCP requests, according to multiple LB-algorithms (busyness, weighted-busyness, round robin, traffic, etc). Another important feature that we cannot live without is the username/passwd authentication for legacy systems that had none."

"The solution is user-friendly and efficient."

"We use it as a load balancer for our application servers."

More HAProxy pros

Cons

"A10 Networks Thunder ADC could improve on the Application Delivery Controller. it's not a fully-fledged web application firewall solution. For example, application data and support need to improve."

"The tool's load-balancing feature should improve."

"The costs can be quite high."

"The solution does logging, but the logging capacity is really small. Because we have a bunch of traffic here, we usually get a logging-side warning that "This many logs were lost because of the heavy traffic." If the logging was better, that would be very good."

"The user interface is not as pretty as it could be."

"In my opinion, they need to improve their cloud support. There is support for cloud, but not all functions are there, such as high-availability."

"There is room for improvement in the upgrading process. Sometimes we have to contact A10 for verification of some stuff."

"Currently, the solution's WAF features are fewer. They should consider increasing their WAF features."

More A10 Networks Thunder ADC cons

"The reconfigurability in terms of the tooling could be improved and maybe an editor plugin can be added."

"If nbproc = 2, you will have two processes of HAProxy running. However, the stats of HAProxy will not be aggregated, meaning you don't really know the collective status in a single point of view."

"HAProxy could do with some good combination integrations."

"Pricing, monitoring, and reports can be improved."

"Improving the documentation with multiple examples and scenarios would be beneficial. Most users encounter similar situations, so having a variety of scenarios readily available on the tool's website would be helpful. For instance, if I were part of the HAProxy team, I'd create a webpage with different scenarios and provide files for each scenario. This way, users wouldn't have to start from scratch every time."

"We would like to see dynamic ACL and port update support. Our infrastructure relies on randomly allocated ports and this feature would allow us to update without restarting the process."

"The logging functionality could use improvement, as it is a little cryptic."

"Maybe HAProxy could be more modular."

More HAProxy cons

Pricing and Cost Advice

"Pricing is one of the features of the product that influence customers to use the product."

"The price of the maintenance support is too expensive."

"The pricing is a third of the price of the F5 competition."

"One of the main reasons for switching away from Cisco was the licensing model. A10 gives you global server load balancing for free, while Cisco charged a significant licensing fee for that."

"It is $7000 per unit for the support annually."

"We previously had F5 and switched because of costs."

"As for the initial investment in the hardware, F5 and A10 are quite similar now. For the current A10 solution, the initial cost was about $36,000. As for annual support, the F5 solution would be between $10,000 and $12,000, while the A10 is $2,200 a year for support."

"For the hardware and license, we paid $35,000 per box, which was a one-time cost. Then, for the Gold Support on the two boxes, we pay $9400 annually."

More A10 Networks Thunder ADC pricing and cost advice

"The only cost is for the image manager, who is responsible for uploading the image, and that is trivial."

"HAProxy is free in the initial offer. However, pricing can be improved."

"When it comes to pricing HAProxy is free."

"HAProxy is a free open-source solution."

"HAProxy is free software. There are optional paid products (support/appliances)."

"HAProxy is an open-source solution."

"If you don't have expertise then go with the licensed version. Otherwise, open-source is the best solution."

"I use the open-source version of the product. I don't have experience with the licensed version of the solution."

Reviews from Real Users

“Having the right load balancing solution – which is what HAProxy is – and protection in place gives organizations peace of mind.” - Nathanel S., Platform Architect at SES

“I use HAProxy for individuals who can not buy low balancers. I built NFV in a box and send individuals a pathway into an HAProxy VM. The setup was not difficult; it usually takes a day to complete for a VPC. When it comes to pricing, HAProxy is free.” - Nasir O., Network & Cloud Architect at Koala Compute Inc.
